Description

  

      Verfahren    zur     Herstellung    eines neuen     Pyrimidinderivates.       Gegenstand des vorliegenden Patentes bildet  ein Verfahren zur Herstellung eines neuen       Pyrimidinderivates,    welches dadurch gekenn  zeichnet ist, dass man ein     Pyrimidinderivat     der Formel  
EMI0001.0006     
    in welcher X einen durch Reduktion in die       Aminomethylgruppe        überführbaren    Rest be  deutet,     mit    einem Reduktionsmittel behandelt.  



  Der Rest X kann beispielsweise in einer       Cyanogruppe    oder einer     Carbamidgruppe    be  stehen. Im ersteren Falle kann die     Cyano-          gruppe    leicht     mit        Raney-Nickel    und Wasser  stoff vorteilhaft in alkoholischem Ammoniak  als Lösungsmittel     reduziert    werden oder auch  mit     Lithiumaluminiumhydrid    in Äther,     Tetra-          hydrofuran    usw.  



  Die     Carbamidogruppe    kann mit     Hilfe    von       Alkali-aluminium-    oder     -borhydriden    in die       Aminomethylgruppe    übergeführt werden.  



  Das so erhaltene     2-Benzylmercapto-4-amino-          5-aminomethyl-pyrimidin    bildet farblose Kri  stalle, die bei 116-117  schmelzen. Es soll als  Chemotherapeutikum und als Zwischenpro  dukt verwendet werden.         Beispiel:

       12,2 g     2-Benzylmercapto-4-amino-5-cyan-          pyrimidin    in 100     cm3        abs.        Tetrahydrofuran     werden langsam zu einer Lösung von 5,8 g       Lithiumaluminiumhydrid    in 100     cM3        Tetra-          hydrofuran        zugetropft.    Das Ganze wird 24  Stunden stehengelassen, dann mit Wasser  versetzt und alkalisch gemacht. Die ausgefal  lene Masse wird getrocknet und     aiis        Petrol-          äther    umkristallisiert.

   Man erhält so das     2-          B        enzylmercapto-4-        amino    - 5 -     aminomethyl-pyr-          imidin    in farblosen, bei 116-117  schmelzen  den Kristallen.



      Process for the preparation of a new pyrimidine derivative. The subject of the present patent is a process for the preparation of a new pyrimidine derivative, which is characterized in that a pyrimidine derivative of the formula
EMI0001.0006
    in which X denotes a radical which can be converted into the aminomethyl group by reduction, treated with a reducing agent.



  The radical X can be, for example, in a cyano group or a carbamide group. In the former case, the cyano group can easily be reduced with Raney nickel and hydrogen, advantageously in alcoholic ammonia as a solvent, or with lithium aluminum hydride in ether, tetrahydrofuran, etc.



  The carbamido group can be converted into the aminomethyl group with the aid of alkali aluminum or borohydrides.



  The 2-benzylmercapto-4-amino-5-aminomethyl-pyrimidine thus obtained forms colorless crystals which melt at 116-117. It is intended to be used as a chemotherapeutic agent and as an intermediate product. Example:

       12.2 g of 2-benzylmercapto-4-amino-5-cyano-pyrimidine in 100 cm3 of abs. Tetrahydrofuran are slowly added dropwise to a solution of 5.8 g of lithium aluminum hydride in 100 cM3 of tetrahydrofuran. The whole thing is left to stand for 24 hours, then water is added and the mixture is made alkaline. The precipitated mass is dried and recrystallized using petroleum ether.

   The 2-benzylmercapto-4-amino-5-aminomethyl-pyrimidine is thus obtained in colorless crystals which melt at 116-117.
